Yes we were worried, we didn't like it. But weirdly, as many people pointed out at the time, no one is likely to have dared accost a little girl with the number of drug dealers hanging around who would have protected them 😂I am joking a bit, but not entirely, because in a way it was true.
Anyway, we did enforce collection at the end of the evening in the dark, but nothing we could do if a child just took off, and of course nothing we could do if they were arriving alone.
And in many years, nothing bad ever happened.
The biggest problem on Thamesmead is drugs, particularly cannabis, and the related paranoia, psychosis, etc which leaves people unemployable. But it is a minority. As a teacher, I am aware of the dangers of getting drawn into drug dealing for our young teens, and into money laundering (worse, more insidious and the brighter, more ambitious children are easily ensnared)
It isn't particularly bad though. I have worked in other areas and this one is not a lot worse, than say a more affluent looking town in Berkshire.
People are insulting Thamesmead without any knowledge of it. Yes, some very poor people live here. But they are not all druggies and criminals, you know! Many are hard working, intelligent and aspirational.
